Joey is buying plants for his garden. He wants to have at least twice as many flowering plants as nonflowering plants and a mini

mum of 36 plants in his garden. Flowering plants sell for $8, and nonflowering plants sell for $5. Joey wants to purchase a combination of plants that minimizes cost. Let x represent the number of flowering plants and y represent the number of nonflowering plants.
What are the vertices of the feasible region for this problem?

a. (0,0) (0,36) (24,12)
b. (0,36) (24,12)
c. (0,36) (24,12) (36,0)
d. (24,12) (36,0)

<h2>Answer:</h2>

The vertices of the feasible region for this problem is:

      d.       (24,12) (36,0)

<h2>Step-by-step explanation:</h2>

Let x denote the number of flowering plants

and y denotes the number of non-flowering plant.

It is given that:

He wants to have at least twice as many flowering plants as nonflowering plants.

This means that the inequality which will be formed is given by:

           x\geq 2y

and he must have a minimum of 36 plants in his garden.

This means that the inequality is given by:

                 x+y\geq 36

Also,  Flowering plants sell for $8, and nonflowering plants sell for $5.

He wants to t minimizes cost.

so, the optimal function is given by:

Cost  Min. c= 8x+5y

The system is written as:

Optimal function    Min. c= 8x+5y

Constraints             x\geq 2y----------(1)

                      and   x+y\geq 36-------(2)

Now, we know that the feasible solution is one which satisfy all the constraints.

Hence, we will check each of the options whether they satisfy constraints or not.

a)

   (0,0) (0,36) (24,12)

when we put (0,0) in constraint (2) we get:

           0≥ 36 which is a false relation.

Hence, option: a is incorrect.

b)

     (0,36) (24,12)

when we put (0,36) in the first constraint we get:

         0 ≥ 72

which is again a false identity.

Hence, option: b is incorrect.

c)

(0,36) (24,12) (36,0)

This option is incorrect.

( Because as done in option: b

(0,36) do not satisfy the constraint (1))

d)

             (24,12) (36,0)

  • (24,12)

        when we put x=24 and y=12

          we see that it satisfy both the constraint

  • (0,36)

     when we  put x=0 and y=36 we will observe that it satisfy both the constraints.

     Hence, the correct answer is: Option: d

A step by step answer please
Allushta [10]

Answer:

7.92 m.

Step-by-step explanation:

Mean height = ∑(f . x) / ∑f  where  x is the midpoint and f the frequencies

The midpoints for the heights are:

2 for frequency 8              ( 0 + 4)/ 2 = 2

6 for      ..           21

10 for    ..            12

14 for    ..              7

18 for   ..               2

So the mean is:

[(2*8) + (6*21) + (10*12) + (14*7) + (18*2) ] / (8 + 21+12+7+2)

= 396 / 50

= 7.92 m.

There are 12 red pens, 20 blue pens and 5 black pens in a bag. What is the probability that you will pick a black pen? Round
Vlada [557]

Answer:

The probability of getting a black pen from the bag is 13.5%.

Step-by-step explanation:

To determine the percentage probability that a black pen will be obtained from the bag, the following calculation must be performed:

12 + 20 + 5 = 37

37 = 100%

5 = X

(5 x 100) / 37 = X

500/37 = X

13.5 = X

Thus, it is determined that the totality of pens is 100%, and through a cross multiplication the percentage of the 5 black pens with respect to the total of pens is obtained.

Therefore, the probability of getting a black pen from the bag is 13.5%.
